[origin: EP1958786A2] A door opening and closing unit (300) is provided for an image forming apparatus (1). The image forming apparatus includes a main body (100), and a door (200) rotatably mounted on the main body. The door opening and closing unit includes a door speed control unit (360) coupling the door to the main body that includes a coupling boss (340); and a guide groove (350) that engages the coupling boss (340) and along which the coupling boss moves as the door rotates relative to the main body; wherein the door speed control unit controls a frictional force between the coupling boss and the guide groove according to a rotating angle of the door relative to the main body to control a rotating speed of the door as the door rotates relative to the main body.
